MTDMettler Toledo · Insider ownership research

Mettler Toledo insiders sold $35.9M in the past 12 months. How much of their stake is that?

About 41% of the shares they held or received (after tax withholding) during the period. The usual measure, against starting holdings alone, can't be used here because most of the shares sold arrived during the period.

No officer or director trades were reported for the past 30 days. The most recent before that:

Aug 27, 2026Patrick Kaltenbach sold 942 shares ($1.3M) with no plan disclosed. That is 17% of the total stake held that day. 942 shares came in from vesting or option exercises the same day, so the holding rose by 0 net.

"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? Less than usual: about half of the 5-year average. 6 insiders sold; the average is 8 a year. Year by year

The filings don't state a reason.Guerroniere de la: largest such sale, Nov 11, 2025 · Shawn Vadala: largest such sale, Aug 3, 2026 · Patrick Kaltenbach: largest such sale, Nov 12, 2025

Percentages cover 13 of 18 officers and directors. 5 are left out

Common questions

Is the Mettler Toledo CEO selling stock?

Yes. Patrick Kaltenbach sold 2.9K shares ($4.3M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Mettler Toledo insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.

Are any Mettler Toledo insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Mettler Toledo insiders sell?

About 41% of the shares they held or received (after tax withholding) during the period. The usual measure, against starting holdings alone, can't be used here because most of the shares sold arrived during the period. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

18 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (18 exactly, 0 with a minor or footnoted difference). Percentages cover 13 of 18 officers and directors. Left out: Thomas Salice (most holdings were last confirmed in 2016); Guerroniere de la (most holdings were last confirmed in 2010); Pablo Perversi, Michael Tokich and Natalia Shuman-Fabbri (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertaintyEvery officer and director reconciles

Inferred typo: the share class "Common Stock, par value $.01 per share" is treated as the same class as "Common Stock, par value $0.01 pershare" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Robert Spoerry, 346,826 shares): old title, new title

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology1,104 filings from SEC EDGAR, and how we read them

All 1,104 Forms 3, 4 and 5 filed for Mettler Toledo (SEC CIK 1037646) from Mar 10, 2003 to Sep 1, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 1 older filing exists only on paper and could not be read.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
